Process summary
The process starts by filing form S-1 with the SEC. The SEC reviews the filing and sends back very detailed comments. The company then files an amendment reflecting these comments. The SEC likely has comments again. This process repeats for 2-3 and sometimes many more iterations until the SEC says it has no further comments. The company then files/prints a "red herring" or Preliminary Prospectus and begins the roadshow. This usually lasts 2 weeks and the offering is priced on the last night of the roadshow and begins trading the next day.
Sample timeline
First SEC review: 30 days
Company prepares response: 5 days
Second SEC review: 15 days
Company response: 3 days
Third SEC review: 7 days
Company response ("red herring" : 2 days
Roadshow: 15 days
Trading begins: 1 day
Total: ~10-12 weeks
